Abstract
The present invention provides an ultrasonic probe and method for making the same is provided which has an advantageous construction and method of assembly. The ultrasonic probe has a segmented ultrasonic transducer having a plurality of individual independent transducers, a plurality of piezoelectric transducers connected to a first end of a respective individual independent transducer; and a plurality of electrical connections electrically communicating each the piezoelectric transducer with a power source.
Claims12
An ultrasonic array transducer comprising:
- a segmented ultrasonic transducer having a plurality of individual independent transducers bonded together by a nonconductive bonding agent, each said individual independent transducer including a piezoelectric crystal bonded to a damping body;
- a connector having a first end and a second end, said connector electrically connecting each said individual independent transducer with a power source, said connector providing an independent electrical path such that each said individual independent transducer is powered independently from a remainder of said individual independent transducers, and
- a grounding connection grounding said individual independent transducers, whereby said connector and said grounding connection forms a complete circuit to energize said individual independent transducers.
